# == Active \Model \API
#
# Includes the required interface for an object to interact with
# Action Pack and Action View, using different Active Model modules.
# It includes model name introspections, conversions, translations, and
# validations. Besides that, it allows you to initialize the object with a
# hash of attributes, pretty much like Active Record does.
#
# A minimal implementation could be:
#
#   class Person
#     include ActiveModel::API
#     attr_accessor :name, :age
#   end
#
#   person = Person.new(name: 'bob', age: '18')
#   person.name # => "bob"
#   person.age  # => "18"
#
# Note that, by default, <tt>ActiveModel::API</tt> implements <tt>persisted?</tt>
# to return +false+, which is the most common case. You may want to override
# it in your class to simulate a different scenario:
#
#   class Person
#     include ActiveModel::API
#     attr_accessor :id, :name
#
#     def persisted?
#       self.id.present?
#     end
#   end
#
#   person = Person.new(id: 1, name: 'bob')
#   person.persisted? # => true
#
# Also, if for some reason you need to run code on <tt>initialize</tt>, make
# sure you call +super+ if you want the attributes hash initialization to
# happen.
#
#   class Person
#     include ActiveModel::API
#     attr_accessor :id, :name, :omg
#
#     def initialize(attributes={})
#       super
#       @omg ||= true
#     end
#   end
#
#   person = Person.new(id: 1, name: 'bob')
#   person.omg # => true
#
# For more detailed information on other functionalities available, please
# refer to the specific modules included in <tt>ActiveModel::API</tt>
# (see below).

#   or +attribute_method_prefix+.
# * Call +define_attribute_methods+ after the other methods are called.
# * Define the various generic +_attribute+ methods that you have declared.
# * Define an +attributes+ method which returns a hash with each
#   attribute name in your model as hash key and the attribute value as hash value.
#   Hash keys must be strings.

# == Active \Model \Callbacks
#
# Provides an interface for any class to have Active Record like callbacks.
#
# Like the Active Record methods, the callback chain is aborted as soon as
# one of the methods throws +:abort+.
#
# First, extend ActiveModel::Callbacks from the class you are creating:
#
#   class MyModel
#     extend ActiveModel::Callbacks
#   end
#
# Then define a list of methods that you want callbacks attached to:
#
#   define_model_callbacks :create, :update
#
# This will provide all three standard callbacks (before, around and after)
# for both the <tt>:create</tt> and <tt>:update</tt> methods. To implement,
# you need to wrap the methods you want callbacks on in a block so that the
# callbacks get a chance to fire:
#
#   def create
#     run_callbacks :create do
#       # Your create action methods here
#     end
#   end
#
# Then in your class, you can use the +before_create+, +after_create+, and
# +around_create+ methods, just as you would in an Active Record model.
#
#   before_create :action_before_create
#
#   def action_before_create
#     # Your code here
#   end
#
# When defining an around callback remember to yield to the block, otherwise
# it won't be executed:
#
#  around_create :log_status
#
#  def log_status
#    puts 'going to call the block...'
#    yield
#    puts 'block successfully called.'
#  end
#
# You can choose to have only specific callbacks by passing a hash to the
# +define_model_callbacks+ method.
#
#   define_model_callbacks :create, only: [:after, :before]
#
# Would only create the +after_create+ and +before_create+ callback methods in
# your class.
#
# NOTE: Calling the same callback multiple times will overwrite previous callback definitions.
#
# source://activemodel//lib/active_model/callbacks.rb#65
module ActiveModel::Callbacks
  # define_model_callbacks accepts the same options +define_callbacks+ does,
  # in case you want to overwrite a default. Besides that, it also accepts an
  # <tt>:only</tt> option, where you can choose if you want all types (before,
  # around or after) or just some.
  #
  #   define_model_callbacks :initialize, only: :after
  #
  # Note, the <tt>only: <type></tt> hash will apply to all callbacks defined
  # on that method call. To get around this you can call the define_model_callbacks
  # method as many times as you need.
  #
  #   define_model_callbacks :create,  only: :after
  #   define_model_callbacks :update,  only: :before
  #   define_model_callbacks :destroy, only: :around
  #
  # Would create +after_create+, +before_update+, and +around_destroy+ methods
  # only.
  #
  # You can pass in a class to before_<type>, after_<type> and around_<type>,
  # in which case the callback will call that class's <action>_<type> method
  # passing the object that the callback is being called on.

# == Active \Model \Dirty
#
# Provides a way to track changes in your object in the same way as
# Active Record does.
#
# The requirements for implementing ActiveModel::Dirty are:
#
# * <tt>include ActiveModel::Dirty</tt> in your object.
# * Call <tt>define_attribute_methods</tt> passing each method you want to
#   track.
# * Call <tt>[attr_name]_will_change!</tt> before each change to the tracked
#   attribute.
# * Call <tt>changes_applied</tt> after the changes are persisted.
# * Call <tt>clear_changes_information</tt> when you want to reset the changes
#   information.
# * Call <tt>restore_attributes</tt> when you want to restore previous data.
#
# A minimal implementation could be:
#
#   class Person
#     include ActiveModel::Dirty
#
#     define_attribute_methods :name
#
#     def initialize
#       @name = nil
#     end
#
#     def name
#       @name
#     end
#
#     def name=(val)
#       name_will_change! unless val == @name
#       @name = val
#     end
#
#     def save
#       # do persistence work
#
#       changes_applied
#     end
#
#     def reload!
#       # get the values from the persistence layer
#
#       clear_changes_information
#     end

#   person.name_change    # => [nil, "Bob"]

#

#
#   person.save
#   person.changed?      # => false

#   person.name_previously_changed?(from: nil, to: "Bill") # => true

#   person.rollback!
#   person.name          # => "Bill"
#   person.name_changed? # => false
#

#
# Which attributes have changed?
#
#   person.name = 'Bob'
#   person.changed # => ["name"]
#   person.changes # => {"name" => ["Bill", "Bob"]}
#
# If an attribute is modified in-place then make use of
# <tt>[attribute_name]_will_change!</tt> to mark that the attribute is changing.
# Otherwise \Active \Model can't track changes to in-place attributes. Note
# that Active Record can detect in-place modifications automatically. You do
# not need to call <tt>[attribute_name]_will_change!</tt> on Active Record models.
#
#   person.name_will_change!

# include tests that tell you whether your object is fully compliant,
# or if not, which aspects of the API are not implemented.
#
# Note an object is not required to implement all APIs in order to work
# with Action Pack. This module only intends to provide guidance in case
# you want all features out of the box.
#
# These tests do not attempt to determine the semantic correctness of the
# returned values. For instance, you could implement <tt>valid?</tt> to
# always return +true+, and the tests would pass. It is up to you to ensure
# that the values are semantically meaningful.
#
# Objects you pass in are expected to return a compliant object from a call
# to <tt>to_model</tt>. It is perfectly fine for <tt>to_model</tt> to return
# +self+.

  # Where +XXX+ is the attribute name of your desired password.
  #
  # The following validations are added automatically:
  # * Password must be present on creation
  # * Password length should be less than or equal to 72 bytes
  # * Confirmation of password (using a +XXX_confirmation+ attribute)
  #
  # If confirmation validation is not needed, simply leave out the
  # value for +XXX_confirmation+ (i.e. don't provide a form field for
  # it). When this attribute has a +nil+ value, the validation will not be
  # triggered.
  #
  # For further customizability, it is possible to suppress the default
  # validations by passing <tt>validations: false</tt> as an argument.

# == Active \Model \Serialization
#
# Provides a basic serialization to a serializable_hash for your objects.
#
# A minimal implementation could be:
#
#   class Person
#     include ActiveModel::Serialization
#
#     attr_accessor :name
#
#     def attributes
#       {'name' => nil}
#     end
#   end
#
# Which would provide you with:
#
#   person = Person.new
#   person.serializable_hash   # => {"name"=>nil}
#   person.name = "Bob"
#   person.serializable_hash   # => {"name"=>"Bob"}
#
# An +attributes+ hash must be defined and should contain any attributes you
# need to be serialized. Attributes must be strings, not symbols.
# When called, serializable hash will use instance methods that match the name
# of the attributes hash's keys. In order to override this behavior, take a look
# at the private method +read_attribute_for_serialization+.
#
# ActiveModel::Serializers::JSON module automatically includes
# the <tt>ActiveModel::Serialization</tt> module, so there is no need to
# explicitly include <tt>ActiveModel::Serialization</tt>.
#
# A minimal implementation including JSON would be:
#
#   class Person
#     include ActiveModel::Serializers::JSON
#
#     attr_accessor :name
#
#     def attributes
#       {'name' => nil}
#     end
#   end
#
# Which would provide you with:
#
#   person = Person.new
#   person.serializable_hash   # => {"name"=>nil}
#   person.as_json             # => {"name"=>nil}
#   person.to_json             # => "{\"name\":null}"
#
#   person.name = "Bob"

# == Active \Model \Validations
#
# Provides a full validation framework to your objects.
#
# A minimal implementation could be:
#
#   class Person
#     include ActiveModel::Validations
#
#     attr_accessor :first_name, :last_name
#
#     validates_each :first_name, :last_name do |record, attr, value|
#       record.errors.add attr, "starts with z." if value.start_with?("z")
#     end
#   end
#
# Which provides you with the full standard validation stack that you
# know from Active Record:
#
#   person = Person.new
#   person.valid?                   # => true
#   person.invalid?                 # => false

#   person.invalid?                 # => true
#   person.errors.messages          # => {first_name:["starts with z."]}
#
# Note that <tt>ActiveModel::Validations</tt> automatically adds an +errors+
# method to your instances initialized with a new ActiveModel::Errors
# object, so there is no need for you to do this manually.

  # If one runs <tt>Person.clear_validators!</tt> and then checks to see what

  # Adds a validation method or block to the class. This is useful when
  # overriding the +validate+ instance method becomes too unwieldy and
  # you're looking for more descriptive declaration of your validations.
  #
  # This can be done with a symbol pointing to a method:
  #
  #   class Comment
  #     include ActiveModel::Validations
  #
  #     validate :must_be_friends
  #
  #     def must_be_friends
  #       errors.add(:base, 'Must be friends to leave a comment') unless commenter.friend_of?(commentee)
  #     end
  #   end
  #
  # With a block which is passed with the current record to be validated:
  #
  #   class Comment
  #     include ActiveModel::Validations
  #
  #     validate do |comment|
  #       comment.must_be_friends
  #     end

  #     def must_be_friends
  #       errors.add(:base, 'Must be friends to leave a comment') unless commenter.friend_of?(commentee)
  #     end
  #   end
  #
  # Or with a block where +self+ points to the current record to be validated:
  #
  #   class Comment
  #     include ActiveModel::Validations
  #
  #     validate do
  #       errors.add(:base, 'Must be friends to leave a comment') unless commenter.friend_of?(commentee)

  # Note that the return value of validation methods is not relevant.
  # It's not possible to halt the validate callback chain.
  #
  # Options:
  # * <tt>:on</tt> - Specifies the contexts where this validation is active.
  #   Runs in all validation contexts by default +nil+. You can pass a symbol
  #   or an array of symbols. (e.g. <tt>on: :create</tt> or
  #   <tt>on: :custom_validation_context</tt> or
  #   <tt>on: [:create, :custom_validation_context]</tt>)
  # * <tt>:if</tt> - Specifies a method, proc, or string to call to determine
  #   if the validation should occur (e.g. <tt>if: :allow_validation</tt>,
  #   or <tt>if: Proc.new { |user| user.signup_step > 2 }</tt>). The method,
  #   proc or string should return or evaluate to a +true+ or +false+ value.
  # * <tt>:unless</tt> - Specifies a method, proc, or string to call to
  #   determine if the validation should not occur (e.g. <tt>unless: :skip_validation</tt>,
  #   or <tt>unless: Proc.new { |user| user.signup_step <= 2 }</tt>). The
  #   method, proc, or string should return or evaluate to a +true+ or +false+
  #   value.
  #
  # NOTE: Calling +validate+ multiple times on the same method will overwrite previous definitions.
  #
  # source://activemodel//lib/active_model/validations.rb#152
  def validate(*args, &block); end

  # This method is a shortcut to all default validators and any custom
  # validator classes ending in 'Validator'. Note that Rails default
  # validators can be overridden inside specific classes by creating
  # custom validator classes in their place such as PresenceValidator.
  #
  # Examples of using the default rails validators:
  #
  #   validates :username, absence: true
  #   validates :terms, acceptance: true
  #   validates :password, confirmation: true
  #   validates :username, exclusion: { in: %w(admin superuser) }
  #   validates :email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i, on: :create }
  #   validates :age, inclusion: { in: 0..9 }
  #   validates :first_name, length: { maximum: 30 }
  #   validates :age, numericality: true
  #   validates :username, presence: true
  #
  # The power of the +validates+ method comes when using custom validators
  # and default validators in one call for a given attribute.
  #
  #   class EmailValidator < ActiveModel::EachValidator
  #     def validate_each(record, attribute, value)
  #       record.errors.add attribute, (options[:message] || "is not an email") unless
  #         /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i.match?(value)
  #     end
  #   end
  #
  #   class Person
  #     include ActiveModel::Validations
  #     attr_accessor :name, :email
  #
  #     validates :name, presence: true, length: { maximum: 100 }
  #     validates :email, presence: true, email: true
  #   end
  #
  # Validator classes may also exist within the class being validated
  # allowing custom modules of validators to be included as needed.
  #
  #   class Film
  #     include ActiveModel::Validations
  #
  #     class TitleValidator < ActiveModel::EachValidator
  #       def validate_each(record, attribute, value)
  #         record.errors.add attribute, "must start with 'the'" unless /\Athe/i.match?(value)
  #       end
  #     end
  #
  #     validates :name, title: true
  #   end
  #
  # Additionally validator classes may be in another namespace and still
  # used within any class.
  #
  #   validates :name, :'film/title' => true
  #
  # The validators hash can also handle regular expressions, ranges, arrays
  # and strings in shortcut form.
  #
  #   validates :email, format: /@/
  #   validates :role, inclusion: %w(admin contributor)
  #   validates :password, length: 6..20
  #
  # When using shortcut form, ranges and arrays are passed to your
  # validator's initializer as <tt>options[:in]</tt> while other types
  # including regular expressions and strings are passed as <tt>options[:with]</tt>.
  #
  # There is also a list of options that could be used along with validators:
  #
  # * <tt>:on</tt> - Specifies the contexts where this validation is active.
  #   Runs in all validation contexts by default +nil+. You can pass a symbol
  #   or an array of symbols. (e.g. <tt>on: :create</tt> or
  #   <tt>on: :custom_validation_context</tt> or
  #   <tt>on: [:create, :custom_validation_context]</tt>)
  # * <tt>:if</tt> - Specifies a method, proc, or string to call to determine
  #   if the validation should occur (e.g. <tt>if: :allow_validation</tt>,
  #   or <tt>if: Proc.new { |user| user.signup_step > 2 }</tt>). The method,
  #   proc or string should return or evaluate to a +true+ or +false+ value.
  # * <tt>:unless</tt> - Specifies a method, proc, or string to call to determine
  #   if the validation should not occur (e.g. <tt>unless: :skip_validation</tt>,
  #   or <tt>unless: Proc.new { |user| user.signup_step <= 2 }</tt>). The
  #   method, proc, or string should return or evaluate to a +true+ or
  #   +false+ value.
  # * <tt>:allow_nil</tt> - Skip validation if the attribute is +nil+.
  # * <tt>:allow_blank</tt> - Skip validation if the attribute is blank.
  # * <tt>:strict</tt> - If the <tt>:strict</tt> option is set to true
  #   will raise ActiveModel::StrictValidationFailed instead of adding the error.
  #   <tt>:strict</tt> option can also be set to any other exception.
  #
  # Example:
  #
  #   validates :password, presence: true, confirmation: true, if: :password_required?
  #   validates :token, length: { is: 24 }, strict: TokenLengthException
  #
  #
  # Finally, the options +:if+, +:unless+, +:on+, +:allow_blank+, +:allow_nil+, +:strict+
  # and +:message+ can be given to one specific validator, as a hash:
  #
  #   validates :password, presence: { if: :password_required?, message: 'is forgotten.' }, confirmation: true
  #
  # @raise [ArgumentError]
  #
  # source://activemodel//lib/active_model/validations/validates.rb#106
  def validates(*attributes); end

  # This method is used to define validations that cannot be corrected by end
  # users and are considered exceptional. So each validator defined with bang
  # or <tt>:strict</tt> option set to <tt>true</tt> will always raise
  # <tt>ActiveModel::StrictValidationFailed</tt> instead of adding error
  # when validation fails. See <tt>validates</tt> for more information about
  # the validation itself.
